Abstract: Precise kinematic differential positioning using GPS requires the use of carrier phase observations with1 correctly resolved integer ambiguities. On-the-fly (OTF) ambiguity resolution, i.e. ambiguity resolution while the receiver is in motion, is desirable, since it increases the flexibility and reliability of the kinematic positioning. It is, however, not an easy task. Several factors must judiciously be taken into consideration. One of these is a fast and reliable OTF ambiguity resolution technique. OTF ambiguity resolution techniques generally resolve ambiguities by testing many combinations of ambiguity sets or positions representing the ambiguity sets inside a certain predetermined searching space. The shape and size of the searching space affect tile speed of ambiguity resolution. In this paper, the construction of the optimal searching space is explained and discussed, and results based on a static zero baseline GPS data collection are presented. It is shown th
